The third person arrested in connection with the Delhi high court blast -- Amir Abbas Dev -- was remanded to seven days of police custody by a local court to enable the security agencies to question him.
The accused was produced before Principal District and Sessions Judge Kishtwar on Friday who remanded him to custody for questioning him at length for helping in sending an email barely two hours after the September seven blast.
He is being interrogated by a joint team of interrogators of J and K Police and National Investigation Agency (NIA).
Dev was arrested on Thursday as per the court records even as NIA chief Sharad Chandra Sinha had denied it in Delhi last night.
"...Whatever appeared in media regarding the course of investigation is speculative in nature and is denied," he had said.
Dev is accused of handing over draft mail three days before the blast to two high school children -- Shariq Ahmed and Abid Hussain. The two children were the first one's to have been arrested by the police for sending the mail.
As sleuths were still struggling for a breakthrough to trace the main perpetrators of the September seven blast, the sources said there was a possibility that the two could be part of a larger conspiracy behind the terror strike.
Dev is alleged links with a religious organisation and was picked up after detailed interrogation of the two boys arrested yesterday, the sources said. He is suspected to have been involved in brainwashing youths to join the militant ranks.
